**VL82C380         Single chip 386DX PC/AT Controller +on-chip cache ?
***Info:
VLSI  Technology,  Inc.'s  VL82C380  is  a  highly  integrated  32-bit
single-chip PC/AT  controller with  on-chip cache  controller designed
for use  in 386DX-based  ISA systems  operating at up  to 40  MHz. Its
cache  controller   is  designed   with  a  look-aside,   write-  back
architecture  for   increased  write  performance  as   well  as  read
performance.  Full  coherency  is maintained  during  DMA/Master  Mode
cycles.

The VL82C380 is  a highly integration solution. A  complete system can
be implemented  using only  the CPU,  BIOS, DRAM,  VL82C380, VL82C113A
Combination I/O and 3 SSI TTL's, plus optional TAG and Data SRAMs.

Tag SRAMs  can be either  8- or  9-bit (7- or  8-bit tag plus  a dirty
bit). Dirty and Valid bits are optional, each may be disabled in order
to increase cacheable DRAM range.  The Dirty bit, when used, indicates
that the cache has been updated but not the corresponding locations in
DRAM. The  Valid bit,  when used,  indicates that  both the  cache and
corresponding DRAM locations have been updated.

Only  on-board   DRAM  is  cached,  this   prevents  coherency  issues
associated with caching  system memory in the USA  bus. Full coherency
is  maintained   during  DMA/Master  mode  cycles,   so  flushing  and
invalidating   operations   are    unnecessary.   set-up/sizing   mode
(programmable) provides direct access to the cache data SRAMs.

The Memory Controller logic is capable of accessing up to 64 MB. There
can be up to 4 banks of 256K,  1M, or 4M DRAMs used in the system. The
VL82C380  can drive  two  banks without  external buffering.  Built-in
page-mode  operations  and  up  to 2-way  interleaving  allow  the  PC
designer    to   maximize    system    performance   using    low-cost
DRAMs. Programmable DRAM timing is  provided for RAS precharge, RAS to
CAS delay, and CAS pulse width.
